At Christmastide, we celebrate the light that has come into the world to illumine us all, and the Kingdom of Light our God ushered into existence. It is the Kingdom of the light of our God. Isaiah the prophet wrote, “Come, descendants of Jacob, let us walk in the light of the Lord.” To walk in the light of the Lord is to walk as His called-out ones, His true followers. And the Apostle Paul wrote “For once you were darkness, but now in the Lord you are light. Live as children of light.” What a gift we celebrate in the advent of our Savior, and in the incarnation of the light of God.
